            Bug ID: 259340
           Summary: ftp/netdumpd: ability to restrict response port range
                    to enable corporate firewall use

          Priority: ---

netdumpd receives HERALD requests on 20023 by default, and returns a random
port to accept the response from the remote client.

To help working in cloud & bigcorp environments, it would be useful to allow a
one-off invocation of netdumpd on a fixed response port, or restrict the port
range that netdumpd will support accepting responses on.
